Wiring diagram for NB-dash-clock

Hi,

I recently bought a 2nd hand NB dashboard-clock for my NA Miata. The
previous owner couldn't tell me anything about how to wire the thing and I
don't want to go the trial-and-error way possibly resulting in blowing up
the electronics.

I'm talking about this clock:
http://www.xs4all.nl/~jfeelder/images/klok.jpg. On the back is a 16-pole
male connector (1-8, 9-16). By looking at the print poles 1, 3, 8, 9 and 10
are used. The plastic cover says: 1:TNS(-), 6:GND, 8:B(+), 15:TNS(+),
16:ACC.

I can imagine 3 wires are needed (unswitched 12V+, -/GND and dimmable 12V+
for backlight display).

Can someone give me any directions? Maybe someone can let me know what wires
are connected on the female (in-car) connector?
